Hose-NozzLE.

SPECIFICATION forming part of Letters Patent No. 294,675, dated March 4, V1884:'. .i

Application led September 20,1SE3. (No model.)

To cir/ZZ whom, it may concern.-

Be it known that I, JOSEPH RICHTER, acitizen of the-United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hose-Nozzles, of which the following is a specification.

Thisy invention relates to improvements in hosenozzles, and has for its object to provide novel and efficient means whereby a solid or a spray stream can be thrown 5 to which and other ends the invention consists in the construction and combination of devices hereinafter described and claimed, reference being had to the accompanying drawings, in which-- Figure l is a longitudinal central section of my improvement. Fig. 2 is an elevation of the piston and cut-oif valve removed from the nozzle.'

4A represents the barrel of the nozzle; B, a detachable nozzle; C, a packing-box for the valve-stem; D, apiston. The forward end, c, of this piston is used as a throttling-stem for the oriiice a in the nozzle D.

d represents wings formed on piston D, to act as guides to hold point o centrally in relation to orifice a., the bore in the forward end of barrel A being straight or cylindrical backward as far as the guides d are made to travel.

E .represents the cut-off valve, which is formed on the rear end of piston D, so as to seat with the pressure against seat c.

F represents a valve-stem, which is journaled in packing-box C, and the lower end has a stem, j', which journals in ledge g.

G represents a crank on the valve-stem F. Y H represents a slot or` mortise pierced centrally through pistonl D.

I I represent ilanges projecting up from the top face of slot H, which is sufliciently cut down from the top of piston D toallow of the free movement of crank G. The bottom of the ribs each side of slot II are planed off, and rest on ledge j" `and vertically support the rear of piston D.

K represents wings on pistonD,which form guides to prevent lateral movementof the rear end yof piston D.

, Fig. l represents the pistonD retracted and the nozzle open for throwing a solid stream of water. Then it is desired to adjust the nozzle and piston for throwing water in the form of spray, handle T of valve-stem F is turned till crank G comes in contact with the forward ledge, vI, when it moves piston D forward until its point c is carried into orifice a, a sufficient distance to break the solid stream. To more effectually accomplish this,small groovesoare cut in the forward end of point c. To cut ofi the water, the handle T is turned till crank G has carried piston D forward to the farthest extent, when valve E will rest on yits seat c andclose off all of the water. The crank and piston are so adjusted that the crank is in alongitudinal plane with the piston when the valve E is opened or closed, its position being the reverse of that shown in Fig. l when the valve is closed and the water shut off.

I am aware that ahose-nozzlehas heretofore been made in which a valve-stem is reciprocated by a crank-pin on a handle journaled in the barrel, said stem having at its rear end a cut-off valve, guides for centering it in the barrel, and at its forward end an enlarged piston, the periphery of which -is grooved spirally, and such therefore I disclaim.

l. The combination ofthe barrelA, the noz zle B at the outer end thereof, having the orifice a, the piston D, having a stem, c, at one end, for entering the orifice in the nozzle at the outer end of the barrel to convert the solid stream of water into a spray, a cut-off valve at the other end of the piston, and means for shifting the piston longitudinally.

2. The combination, with the barrel A, its valve-seat c, and the nozzle B at the outer end of the barrel, having the orifice (t for throwing a solidstream, of the piston' D, having' at one end the stem c, for entering the orifice of the nozzle at the outer end of the barrel to convert the solid stream into aspray,said piston having at its other end the cut-off valve Eand the slot H, and a crank journaledin the barrel and eX- tendingthrough the slot, said crank having a stem, j, at its lower end,seated in a part of the barrel, substantially as described.

8. The combination, with the barrel A, hav- I IOO piston having betweenits stem c and the crank the lateral lamide-Wings d d, to hold the said stein centrally in relation to the orifice of the nozzle, substantially as described.

In testimony whereof I have hereunto set i 5 my hand.
